Application led June 28,

To all whomz'tmay cof/wem.' Be -it known that I, ALBERT OLIVER, a citizen of the United States, and a resident of New York-city, in the county and State of New York, have invented new and useful Improvements in Plaster-Ground, of which the following is a full, clear, and exact description. j'

Among the principal objects which the present invention has in view are: to prevent fractures in plastered or cemented surface structures; to provide a metal bond for concrete structures for dissipating lines of fracture in the cement; to reduce the necessary thickness in wall structures; to save concrete; and to insure uniform thickness to concrete wall structures.

. Description.

Heretofore, ,reinforced sheathing having a suitable paper vor fabric backing has been usedin connection with suspension rods vand.

an auxiliary netting or wire fabric of lighter.l grade. Also wire fabric has been emp oyed as a covering for wood sheathing of suitable..

construction. The former method of construction has proved objectionable in that,

lines of fracture have been established par? allel with the reinforcing rods.

The wire fabric above referred to has been employed in an .endeavor to check or dissi ate these fissures or lines of fracture. Whi e, to some extent, they have been suc! g VNi cessful they have established another objecl tion, in that the concrete when disposed on Specication ofLetterl Patent.

`1919. serial No. 307,;399. lthe rods, has been laid in established lines or areas in which the various thicknesses on established lines have promoted fracture of the material along these lines.

Objection vhas existed to the use of the ground -on the wood sheathing or siding in that, `certain building structures are not readlly adapted to the employment of wood sheathing, and further that, when wood is employed, a surface drying occurs whichis not desirable for the concrete face.

The above stated objections are overcome in the present invention wherein the numeral 10 is used to designate a sheet of heavytarred or building paper which has been rendered waterproof. Superposed on the sheet l0 is a continuous sheet of metal fabric in which the hanging rods 11 are structurally united by interwoven binding wire 12. The wire 12 is weaved upon the rods 11 to form connections therewith and projections '13 at the junction of said wire and said rods. It will be understood that the meshed sheet`is made inJ relatively narrow lengths of any desired dimension and generally'inY accordance with building specification so that the rods 11 are suspended from the floor meshed sheet which has been laid on the.

table and a second meshed sheet is then superposed on the continuous sheet.

As seen best in Fig. 2 of'the drawings..

` care is exercised to arrange the meshed sheets insuch manner that the rods 11 are in the same plane or juxtaposed in close relation to one another with the sheet 10 intervening. In this position, metal clips, staples or tie members 14 are driven throu h `the paper sheet 10 and' bound around t eV rods 11, the ties being twisted until the rods 'are drawn tightly upon the intervening paper sheet 10.

As seen best clips 14 are preferably staggered in their relation to form triangularly related points of attachment.

When grounds are thus constructed, it will be observed thatv the paper is firmly supported to resist any usual strain imposed in Fig. 1 of the drawings, the

the plaster or concrete, the method thereupon when laying the plaster or concrete which is spread by means of trowel or spray. On both faces of the ground when suspended in position, a substantial partition may be thus constructed which occupies a relatively small floor of space. A

When a ground is to be provided havin one surface thereof only prepared to receive referred is to use metal straps 15, which liave upstanding members 16, preferably punched therefrom at intervals corresponding with the intervals between the rods 11. Vhen constructing the ground for spreading the concrete on one side thereof, and when usin the straps 15, the straps 15 are first laid upon the o erating table at suitable intervals in paralle relation with the members 16, preferably in staggered relation. The paper sheets 10 are lthen overlaid upon straps 15 and pressed thereon to force the members 16 therethrough. The paper .thereafter serves to steady the osition of the straps 15.

. The meshed) sheet is then overlaid upon the paper sheet with the rods 11 extendin transverse the straps 15, each of the said rods being disposed adjacent to or 'uxtaposed to certain of the members 16. n this position, the members 16 are then overlaid upon the adjacent rod 11 and coiled tightly down thereupon, as shown best in Fig. 3 of -wire 12.

the drawin This havin been accomplished, it will be found the s eet 10 and the meshed sheet having the -rods 11 and the connecting wire 12 are held firmly together as a unit.

' A single-faced round may now be suspended on a meta? or other skeleton structure with the meshed sheet disposed outwardly so that concrete or plaster may be spread thereover enterin behind and involving the rods 11 an the connecting It will be noted that the wire 12 and rods 11 are so interwoven that lines offracture will be dissipated if su'ch should occur, and

- the concrete or plaster is held firmly in all directions.

- It will be understocd that when desired,-

the reinforce used at opposite sides of the continuous sheet 10 may vary in lweight and dimension to accommodate constructions where the plastered surfaces are relatively heavy and light, or thick and thin, such as might occur where an exposed surface thickness is formed on one side of the ground,

and an interior surface is formed on the other side of the ground.
